7). A spin 1/2 particle is in an eigenstate of S, with eigenvalue 1/2 at time t = 0. At that time it is placed in a magnetic field of magnitude B pointing in the 2-direction, in which it is allowed to precess for a time T. At that instant, the magnetic field is rotated very rapidly, so that it now points in the w direction. After another time T, a measurement of S, is carried out. What is the probability that a value of R/2 will be found? uto Credit Thte hlaw the trummaban l of the Tan
